First aas cycle!

So the time is here to move to a big boy. I'm 23 been taking ph on an off for some time now and have made pretty good gains. I'm curious if I would just take one cycle of test 300 mgs for 10 weeks with hcg, ai, and Nolva as pct how much would I gain on a clean bulk and would I keep it or most of it if I never took aas again and what kind of test does everyone recommend I know there is a bunch of different ones, just looking to shoot every 3-5 days nothing crazy everyday **** lol any advice
